Electrochemical reactions and charge transport in undiluted room-temperature melts of oligo(ethylene glycol)-based electron carriers

Molecular Design and Morphology Control Towards Efficient Polymer Solar Cells Processed using Non‐aromatic and Non‐chlorinated Solvents

“…Herein we introduced triethylene glycol monoether (TEG) side chains onto the TT units (TT‐TEG) and designed a new polymer, PBDTTT‐TEG ( Scheme ). Previous reports have found that TEG chains possess several obvious advantages over alkyl analogues . For instance, TEG side chains will not cause steric twisting of the polymer; TEG is also known to solubilize conjugated polymers, making a number of non‐aromatic and non‐chlorinated solvents possible.…”

High‐Temperature Electrochemistry of a Solvent‐Free Myoglobin Melt

“…This strategy circumventst he problem of low salt solubility and related conductivity in polymer electrolytes. [21][22][23][24][25][26][27] However, the diffusion coefficients were still found to be on the order of 10 À9 -10 À12 cm 2 s…”

A facile strategy to enhance the fill factor of ternary blend solar cells by increasing charge carrier mobility

“…[27][28][29][30] Previous works found that alkoxy side chains, especially triethylene glycol (TEG) chains, had several advantages over alkyl analogous. [31][32][33] The first is that if the oxygen is directly attached to the fused ring, the bandgap of the polymer can be reduced by a substantial amount. The second is that alkoxy side chains will not cause a detrimental steric twist of the polymer out of planarity which is beneficial for charge transport and can lead to high carrier mobility.…”

“…The third is alkoxy side chains generally lead to good crystallinity which is important to film morphology. [31][32][33][34] TEG has been densely used in optoelectronic applications, and are proved to be a benefit to promote device performance. [34][35][36][37][38][39][40] In photovoltaic applications, TEG derivatives are usually used to modify electrodes as a buffer layer for improving the contact of organic/metal interfaces and enhance the open circuit voltage (V oc ) values.…”
